To all whom it may concern:

Be it known that I, Anens'r W. Annnnr, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in a Plumbers Soil; and I- do hereby declare the following to be a full, clear, and exact description of i the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a plunibers soil. It is aimed to provide a composition of this character which avoids the use of glue or equivalent adhesive so that it may be more readily prepared, or ren'ioved, will re main longer in a viscid or workable condition,'ca n be agreeably handled, which is less expensive and which reduces the proportion of lampblack usually used in plumbers soil and which will be generally more effective and advantageous.

Another object is to provide a plumbers soil in which starch and a syrup are used in combination to impart the viscid consist ency thereto and with the starch further fuctioning to reduce the proportion in which the lampblack must be employed.

In carrying out'the invention, lampbla'clz,

starch and a syrup, preferably molasses, are

used. These ingredients in any suitable proportions, are mixed together intimately so as to form a v'iscid composition. In this raw state the composition may be used. However, it may also be boiled, steamed or heated, if desired.

As one example, two parts of lampblaclr and one part of corn starch by volume are intimately mixed together while in a dry staie'and then mixed with sullicient. molasses to. reduce the mixture to the consistency oi paste.

Said mixture is preferably thinned by means of water before use For instance directly aftercompounding it, it may be di-- Application filed. April 17, 1922. Serial No. 554,188.

added thereto or the applying brush moistened and rubbed on the composition, so that the composition when actually applied will be of the proper or desired consistency.

In the using the composition, the pipes or other parts to be soldered together for instance by means oi a wiped joint as is usuahhave the composition applied thereto at a point beyond the area to receive the solder and to thus confine the area where the solder may adhere or, join the pipes.

The plunibers soil will prevent the solder of the wiped joint from adhering to the joint or other parts beyond the edges of the wiped joint so as to present a neat appearanceor finish to the joint;

Attention is called to the fact that the composition is of such a nature that the ap plication of heat incidental to the wiping of the joint, will not cause the'composition to run or become displaced.

The composition prepared in accordanc with my invention will remain in a viscid state and without spoiling for a consider-- able period of time and it may be readily prepared, not necessarily requiring heat as in the case of the melting of glue I find that the starch imparts an eitec tive body to the molasses and in addition enables the composition to be prepared with the use 0t lampblacl; in a relatively small proportion.

As merely one example of the practice of the invention has been ven, it is to be under I QQPlumbcrs soil having lampblack and- .inolasses therein.

3. Plumbers soil having lanipblaclr, starch and a syrup therein.

In testimony whereof I athx my signature in presence of two'witnesses.
